DESCRIPTION

the Releasble slip fishing spear is an internal catch fishing tool designed to retrieve tubular members from the well bore. It is a rugged,dependable, and inexpensive device. The simple design assures positive engagement throughout the fishing operation, is easy to lease and re-engage if necessary and may be run in conjunction with other equipment such as pack-off attachments and internal cutting tools. Construction
the basic Releasing slip fishing spear consists of mandrel, a grapple, a bull nose nut, and a release ring. the mandrel is made of specially heat treated high strength alloy steel; and may be ordered either as a flush type to enter completely into a fish or as a shoulder type to provide a positive landing position on top of the fish. Size and type of the upper box connection is provided according to customer's exact specifications.
Assembly and operation
First screw the grapple onto the mandrel.(note:this is a left hand thread.) slip the release ring onto the end of the mandrel and make up the nut. Screw the grapple down the mandrel hand tight against the release ring. This puts the tool into the running position.
Make up spear to bottom of fishing string. Run in and position the spear in the fish, then rotate the mandrel one full turn to the left. The grapple should now be engaged. Pulling straight up will cause the tapers on the mandrel to expand the grapple and will allow the grapple to bite into the fish.
To disengage the grapple, bump down and rotate to the right several turns. Pulling straight up should free the spear. When coming out of the fish, continue to rotate slowly to the right.
